Y-cracking in continuously reinforced concrete pavements
… and design was assembled. The model included the concrete pavement, asphalt concrete subbase, and soil subgrade. The effect of areas of changed friction on the direction of principal stress was simulated by considering a patch at the pavement-subbase interaction. Investigated factors related to …

A knowledge base for rehabilitation of airfield concrete pavements
… and designers to solve difficult jointed plain concrete pavement (JPCP) design problems. This expert system focuses on aircraft safety and pavement structural capacity which are key issues for all pavement design participants. During the validation tests, AIRPACS recommendations were compared to …

Life cycle assessment of concrete pavements : impacts and opportunities
The concrete pavement network in the United States plays a crucial role in the economy by enabling the transport of people and goods, but it also leads to resource consumption and environmental impacts. This thesis is fundamentally motivated to reduce the impact that concrete pavements have on …

Performance-Based Evaluation of Joint Sealants for Concrete Pavements
Pavement concrete joints are the weakest locations in concrete pavement systems. They are man-made cracks to accommodate concrete slab expansion and contraction due to temperature fluctuations. Sealant is usually used in pavement joints to prevent roadway debris, deicing chemicals, and moisture …

Stress concentration around dowel bars in jointed rigid concrete pavements
… modeling of the friction and separation at dowel concrete interfaces. The model response was examined for the case of joint loading with an equivalent axle load of 18000 lb. It was found that significantly large tensile stresses develop in the concrete on both sides of the loaded dowel. The …

Field observations of the early-age behavior of jointed plain concrete pavements
Newly constructed rigid PCC highway pavements with open graded stabilized base courses have been found to develop non-uniform, transverse saw-cut joint-crack developments and extensive slab movement behaviors, which cause unwanted premature joint failures. Phase I of this study determined the …

Development of Residual Stress Measurement for Concrete Pavements through Cantilevered Beam Testing
… is important in understanding and predicting a concrete pavement’s performance. However, there is not a standard test for residual stresses in pavements. Prior pavement research was inspired by the hole-drilling straingage method used in metals. This method involves drilling a small hole into …

Effects of Prestress Level and Bond on the Behavior of Prestressed Concrete Pavements
… method of increasing the flexural capacity of concrete. The early application of prestressed concrete pavements was in the mid 1940's but its progress was slow compared with the other types of rigid pavements. Performance of the early build prestressed concrete pavements and advancements in …

Experimental Mechanics of Crack Width in Full-Scale Sections of Continuously Reinforced Concrete Pavements
Continuously reinforced concrete pavements have numerous transverse cracks that occur naturally at variable spacing. These cracks do not affect the performance of the structure unless they widen and result in a loss of load transfer efficiency. The capacity to transfer vertical loads across a crack …

Dowel load transfer systems for full-depth repairs of jointed Portland cement concrete pavements
… in full-depth repairs of jointed Portland cement concrete pavements. Design traffic levels and joint faulting specifications are input to determine maximum allowable bearing stresses in the dowel load transfer system. Adjustments for various levels of reliability, environmental considerations, and …
